Mohammed's Research



WEEK 13

momo.PNG
This is my enzyme assay averages. According to the numbers the values are linear, whcih shows that the assay worked.


momo1.PNG
This is my FPLC result. Unfortunately I lost my protein here. There was supposed to be a peak at lanes 34-36 but there weren't any peaks. The only peaks were the result of residue from previous runs.





WEEK 12

SAM_0635.JPG
This is my dried page gel. Pretty much the same thing as my gel when it was soaking in water except now it is now a bit more distinct. Elution 5, which contains my protein, is barely visible compared to the other bands. Because of this I had to concentrate my protein to 1ml from 5ml.




Serine Threonine Phosphotase 2C from
http://web.expasy.org/cgi-bin/protparam/protparam

Number of amino acids: 324

Molecular weight: 35931.7

Theoretical pI: 5.21

SAM_0628.JPG
My SDS page gell. Starting from the left, Lane 1 is the protein marker, lane 2 was skipped, lane 3 is sample 2, lane 4 is sample 3 (flow through), lane 5 is sample 4 (wash), lane 6 is sample 5 (elution 1) and lane 7 is sample 6 (elution 2) but nothing showed up on that lane.


momo.jpg
This is my nanodrop of elution 1. As it can be seen my concentration of protein is quite low, which is why there is a very thin band in my SDS page gell where the elution one band rests.


WEEK 11

This week I finished my PCR squared and completed my PCR cleanup

Capturemomo.JPG

And I finished up my protein expression.
The Pellet Weight was 2.07g for sample 1 and 2.54 for sample 2.

Absorbance reading to get to 0.1 at 600nm. This was done before trying to get to 0.3.


It took an hour and thirty minutes to get to get to 0.1 absorption
Sample 1 Sample 2
3:00
0.163 0.108
0.193 0.199
0.29 0.28



MohammedCapture2.JPG
This is the absorption of 0.3 at 600nm.



I forgot to take a picture of the pellet but I completed the procedure and the supernatant is in the 4 degree fridge. Also I had two samples but ended up adding too much lysate to sample one so I did my protein purification with sample 2.

WEEK 10

I was not in lab at all this week, well maybe for like 2 to 3 hours, but i will make the hours up for next week. Had three tests and I got pretty sick so sorry about that.
I was supposed to do PCR squared but I will be finishing that next week.
I did my slides for my presentation and talked to Dr.B about them.
Finally fixed my virtual screening.
I started on my Protein Expression but I left too long of a gap so I need to redo it for next week.

So for next week I will finish Virtual Screening of HF9 Library and most probably one other library now that I can do it myself.
Present
Finish all of the PCR
Finish Protein Expression
Will definitely start cloning but don't know if I will be able to finish.


WEEK 9
Mohammed - I think this should be Week 9 - spit up your Week 8 and 9 results.
Good job on the cloning! - Dr. B
1st_run.png
This is the 1st gel run with the first and second PCR runs. The first PCR showed up succesfully as it smeared but unfortunately the second one showed one band but it wasn't very distinctive. This may be due to the fact the blue juice used (6x blue juice) may not have been the right blue juice to use.


Lane 4: 100bp ladder
Lane 5: 2nd PCR
Lane 6: 1st PCR
Lane 7: 1000kb ladder
Lane 8: 1st PCR

2nd_gel.png
This was the second gel for the 1st and 2nd PCR. Again the first PCR showed up but unfortunately the 2nd PCR didn't show up again even though a different blue juice was used. So I have no idea what is happening.


Lane 1: 100 bp ladder

WEEK 7
Did the Primer Overlap Assembly as I designed a set of forward and reverse primers for PCR for serine threonine phosphotase 2C

This is the DNA sequence for the particular target.

Capture1.PNG

This is the oligonucleotides(primers) that I obtained
The protein is serine throenine phosphotase 2C and the strain was made for E.Coli 21
Capture1.PNG


Capture1.PNG

For the particular target there are 24 primers

Also in wet lab I completed the primary and secondary PCR and will do PCR squared this coming week.

WEEK 2




Gel_1.png
This was the first PCR. As it can be seen only the ladder showed up, which means the gel was made correctly but something else went wrong. It may have been incorrect pipetting techniques or other human errors.

WEEK 3 (PCR WITH pGBR22 AGAIN)
_




12.PNG
This is the second gel for PCR with pGBR22. Lane 6 vanished completely and this may have been due to incorrect pipetting techniques as the gel may have been pierced at the bottom. Also lanes 4 and 5 look exactly similar which means that the sample from either lane 5 went to lane 6 or vice versa. Lane 3 is very blurry as it did not run correctlyl.

WEEK 3 (PCR WITH PNIC BSA4)



eco.PNG
Although the bands didn't show (except for lane 4) it wouldn't have mattered as the same concentration was used instead of different ones.


Lane 2: Ladder 100bp
Lane 3: 1 in 1000 concentration
Lane 4: 1 in 1000 concentration
Lane 5: 1 in 1000 concentration


WEEK 4 (PCR WITH PNIC BSA4)
_





GEL_PCR.png
The gen lanes had actually messed up but it was only the last two lanes. Lanes 2-6 did not show at all. This may have been due to incorrect pipetting techniques of the gel may have been more damaged than it was thought.


Lane 1: 100bp ladder
Lane 2: 1 in 100 concentration
Lane 3: 1 in 1000 concentration
Lane 4: 1 in 10000 concentration


ALSO IN WEEK 4 COMPLETED THE PYMOL REFRESHER WHICH IS IN GOOGLE DOCS

WEEK 5 (PCR WITH PNIC BSA 4)

11.PNG
Absolutely nothing went correct on this one. This is probably because the sample were sitting in the refrigerator for a week exactly. That may have interfered with the complexion of the protein.


WEEK 6 (VIRTUAL SCREENING)

Done with both runs 1 and 2 but didn't have time to analyze them. Well ran run 2 on Thursday but had to rerun it on Friday as there was an error in the run. Also did quite a lot of research on my drug. Re did pnic-bsa4 PCR. Samples are in the fridge i jst have to make a gel and analyze them next week.
